SEG Solar SEG-585-BTA-BG 570–585W TOPCon Bifacial Solar Panel

585 Wp
Max Power Output
22.65%
Module Efficiency
144
N-Type TOPCon

Product Overview

The SEG Solar SEG-585-BTA-BG is a high-output bifacial solar panel built for demanding commercial and utility projects. It uses advanced TOPCon technology and a 144 half-cell layout for strong energy capture and dependable field performance. The module delivers up to 585 Wp of rated power and reaches 22.65% efficiency. Its bifacial design helps harvest additional rear-side energy in suitable installations. A durable anodized aluminium frame and anti-reflection coated glass support long service life. With a 15-year product warranty and 30-year power warranty, this panel is designed for long-term value. The wide operating temperature range also supports reliable output in challenging climates.

Key Benefits

High power output: Delivers up to 585 Wp for larger energy yields per module.

Excellent efficiency: Reaches 22.65% module efficiency for strong space utilization.

Bifacial energy gain: Captures light from both sides to improve total system production.

TOPCon cell technology: Supports low attenuation and strong performance in hot conditions.

Long warranty coverage: Includes 15 years for product protection and 30 years for power performance.

How It Works

This module converts sunlight into electricity through 144 high-efficiency half-cells. The TOPCon architecture improves carrier movement and supports strong conversion efficiency. The bifacial build can absorb reflected light from the rear side in installations with suitable ground conditions. The module is also engineered to handle temperature swings and environmental stress. That makes it well suited to commercial rooftops, solar farms, and other large-scale applications. Its electrical profile supports stable string design, while the 1500V system rating helps reduce balance-of-system complexity in larger arrays.

Sunlight conversion: The cells generate direct current when exposed to solar irradiance. The half-cell layout helps reduce resistive losses and improves yield. This supports efficient energy capture across the module surface.

Bifacial rear-side gain: Light reflected from the mounting surface can reach the back of the panel. That additional input can increase total output in the right installation conditions. Performance improves when the structure allows ample reflected light.

System integration: The module operates within a 1500V DC system and supports a 30A series fuse rating. This helps designers build efficient strings for commercial and utility systems. The electrical ratings also simplify planning for large solar arrays.

Customer Success Stories

Troy P

EG4 off-grid base kit, Happy with my purchase.

This is the first stage of my three planned purches. I got the eg4 inverter 6000 XP base kit with six 400 watt panels and the two server rack batteries. Did a little online research and followed the instructions and it got set up without any issues. Right now I'm just running it in my garage on a single outlet and have been running dual 750 watt water distillers with it. Once I get the second inverter and a bunch more panels and batteries, I plan on attaching it to my subpanel in my house that has my lights and outlets and appliances on it. Then I'll get a soft start for my AC and blower and run it on my main panel.

Jacob B

Easy Process, Genuine Support

Trying to pick the correct solar system for your needs can be very technical and frustrating. I wanted to thank Yvhan and the Portlandia Electric supply team for their patience and helpful attitudes through multiple calls. I feel like we were able to narrow it down to what worked for me and my family. My system works great and I couldn't be happier to have picked Portlandia Electric Supply.

Patrick B

Off Grid Solar Purchase

I wanted to get an offgrid solar system for years but didn’t know where to start. I found Portlandia Electric Supply on Facebook and decided to submit a quote. Within 24 hours I had a custom proposal that was almost half the price of the companies I had previously got quotes from. My wife and I decided to order online and the kit came in a timely manner and it was an easy install. Great company to work with!

James Martin

Highly Recommend

I would like to take the time to express the outstanding service that I was provided with by Portlandia Electric Supply. They provided me with all the answers to my questions, and after reviewing our quote over the phone I felt comfortable proceeding to order my kit. It’s exactly what I needed and they were there to help us over the phone when we had questions installing it. I highly recommend others in need to choose Portlandia Electric Supply.

Solar Kit for Mobile Work Van

As a professional videographer, I needed reliable power on the go.Portlandia Electric Supply Delta Pro and roof-mounted panels were the perfect solution. Setup was easy, and the kit included everything needed. The Delta Pro powers my cameras, lights, laptop, and a small fridge with impressive battery capacity.

Keith S

Best Tech Support

You folks have been wonderful guiding me through the ins and outs of going solar. Plus your tech guys Rod and Nelson are the absolute best. They explained all the different aspects of inverters, batteries and how to keep them in top condition. Too much more to put here… but no other company has the 100% tech support you provide for your customers!

Coll A

Great Experience

My experience with Portlandia Electric Supply has been excellent. Before the sales, they answered all my questions to assure that I got what I needed. After the sales they continued to support me with answers and help. I had a warranty issue with a unit, and it was handled as well as possible. I would recommend them to anyone looking to go solar.
